First, your cpp_include_flags should be set to
	cpp_include_flags = [addprefix "-I" [search_list]];

Second, the recipe should read

    obj/%0%.cpp.d: obj/%0%.cpp 
    {
	[c_incl] -nc -ns -nrec
		[cpp_include_flags] [resolve obj/%0%.cpp]
		-prefix "'cascade obj/%0%.cpp ='"
		-suffix "';'"
		[addprefix "-rlp=" [search_list]]
		-o [target];

    }

That is, do not unsplit the -rlp arguments.

This is odd.  There doesn't appear to be a code path capable of exiting
1 without also printing an error message.

If you can produce a small test case which consistently fails I have a
better chance of tracking it down.

You could put a
	setenv SHELL = [shell];
at the top of the cookbook.  This controls the shell used to execute
commands.

This could be it.  The tcsh start-up files, that is,
before c_incl is even run (the shell is exec()ed with a -e argument, so
it aborts at the first error).
